kg ... well we're going into the latest on that resemble those of the most senior ... lethal within UK resigns as John Yates last week he testified before moment ... that every setback ... Lisbon has expressed regret ... that we didn't do enough ... the view that as of potentially affected dogs and ... potentially ... to the line ... on public hands ... okay that was cited units up ... last week pressing column of winning a Bruce Orwall mounted talk more about these in London with a wolf it all the talk more about what's been going on ... with the police force is a pretty big deal we already have the chief of the month long playing ... resigning now this trap only to see a spate of more resignations ... why think these are the two main out ... departures the contest at the time being but over time the can be a lot of we suffer severe wound up in this and I ... assume that there will be more departures as as information comes out and I'm I'm I'm unfolds ... first what about other departures that may ... be seen within NewsCorp itself we were the same ... two executives of stuff down in the last few days is that the end of this or do think that might be more ... well and forcefully we've reached the uncomfortable moment in the saga were the only people left really do want to resign at the last name of Murdoch and so on ... it ... was gonna go any further to go up more interesting I think because they've they've taken the the obvious it's that they can take Rebecca ... Brooks was that ... that that the bulk of the former heads of that of the U K newspaper unit ... Tom who had made various statements are but had various involvement in the summertime and ... andDow ... that that is one big write off on Friday but going forward ... you know it's it's not clear ... how you could come escalate the resignations without taking out ... without ... getting in the family itself so one would have the resonance as we saw last week um to appease the British public that I know that first home was in full fury last week at Alwan news the wealth is much moved on ... I'm any sense that things are coming down ... we're not to have a good sense of that until tomorrow when we get to the idea that the big steam valve on this thing is is this parliamentary hearing tomorrow where ... it's essentially kind about ... the fact profile of Rupert Murdoch for being a pervert rock and got them for running a tabloid newspaper operation that's been ... very hard charging sharp elbowed than ample of pushing for four years and so ... he's going to hear a lot of criticism about both ... of the general way that they've run their business over over time and also the specifics of this phone hacking saga ... another company handle that and that's ... likely to be at the open on pleasant afternoon for ... Rupert and James Murdoch and how they handle that I think well ... I'll call long way to determine how much not how much extra gases in them ... the anchor tenant for the public going forward ... the brewer said the same time there are external investigations ... are going on with respect to NewsCorp in its activities ... I understand that also NewsCorp itself ... as odd as made some moves in terms of investigating its own behavior can you update us on that ... rival that of a they've appointed a Optum a senior ... UK ... criminal lawyer as the head of a ... special independent committee that sworn into our ... investigators Rupert Murdoch said last week supposedly every allegation of improper behavior ... this committee Sari have been ... kicked around a bit in the sense that it was that initially can be headed by Rebecca Brooks who now has resigned and been arrested and ... then was to be headed by Joe Klein on the hop on the scoreboard now it's it's it's being ... taken to the door to a distinguished outside time ... um ... no supposedly independent person ... whether that API's is you know any body with the results this is not clear Rupert Murdoch is ... in the past ... try to use the concept of establishing an independent committee to ... go to ... carried charges that he is torn phase there's too much influence over is that newspapers for example and ... those ... instances of always generate a lot of controversy that are not really ... he did not really independent ... last time but said that the Palm entry into the ring met with them as it seeks more of wet wet Janzen with them of up to ten over pay a ... fee for members all column in ... what's now like we know what it's like in the U S one is a congressional hearing at ... the Senate or House what's the difference the main difference is between the the the with the US of this sort of thing on the way the U K jobs ... well one main difference that if you're member we've all seen congressional hearings without ... executives raising their ... Sezmi their right hand and bass ... wearing a that there to testify under oath ... that the executors appearing tomorrow will be underwrote ... and you know as such ... I don't believe that they are I'm in jeopardy of perjury if they live in the committee ... but that said ... it's obviously not a good idea to shift before this committee and mislead Parliament I can I do think that ... even it's not ... for three per se they're they're there may be ... of a crime of misleading parliament that could expose yourself to ... I'm ... and there's obviously just the Lockerbie case Chileans take for the company right now and doubt ... so ... you know I I I think what you'll see is is basically a ... very theatrical political that not unlike the U S congressional hearing where there be a lot of ... um just grandstanding and ... rhetorical questions ... from the out for members of parliament and some ... difficult the true story the executives to confront ... not Sefina misses question time and on I've seen the opposition sometimes throwing pieces of paper and the prime minister ... is in line to get the heated with with AMP's that will literally loving all jacked ... no this is this is not that ... fortunately for ... Mr Murdoch this is not a top speed was ... shooting at that time this is for or if it had started to have the kind of ... raucous ... I see no sort of atmosphere that use their prime minister's questions every Wednesday which has its own ... unique tradition and doubt ... the very unruly environment this is this about the ... opposition's shouting out of the ... prime minister and vice versa ...
